HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 707,990, dated August26,

Application filed November 19,1901. Serial No. 82,905. CNo model.) a

T on whom it may concern.-

Be it known that I, WILLIAM VOGEL. a citi zen of the United States, anda resident of Hartley, in the county of OBrien and State I p The objectof thisinvention is to provide a simple, cheap, and efiectiveheatingdrum which is connected to the smoke-pipe of a stove, so that theproducts of combustion or smoke'will be caused to take a circuitousroute through the drum, and thereby produce a greater heat-radiatingsurface, provision being made for allowing the smoke to pass directlythrough the drum to give the required draft to the'stove when needed.

The invention also contemplates a peculiar construction and arrangementof partitionplates in the drum to provide for the direct and circuitouspassages for the smoke and to also provide for effectually cleaning thedrum of ashes.

The following specification entersinto a detail description of myinvention, reference being had to the accompanying drawings and toletters thereon, which designate the different parts, and what I claimin the particular construction and combination is more specifically setforth in the appended claims.

In the drawings which form a part of this specification, Figure 1 is aside elevation of a heating-drum constructed in accordance with myinvention. Fig. 2 is a vertical longitudinal sectional View. Fig. 3 is aview showing a drum provided with the horizontal partition-plates only.Fig. 4 is a longitudinal sectional View of one of the partition-plates.Fig. 5 is a transverse sectional view of one of said plates. I

Referring to said drawings, A-designates the casing of the heating-drum,which is connected at its lower end directly to the stove by a shortpipe (I. and at its upper end to a pipe at, which extends to the chimneyor flue. Though I have shown this casing connected directly to the stoveby a short pipe, it will be understood, of course, that the drum may belocated in another room from the stove and connected thereto by pipe.The casing is preferably rectangular or square in shape, though it maybe oval or round.

Located in the upper part of the casing A are a number ofpartition-plates B, arranged horizontally and disposed in difierentplanes, 5 3 the said plates projecting alternately from opposite sidesof thcasing to provide a cir-' cuitous passage for the smoke. Each plateis fastened to a rod b, which is swiveled in the sides of the casing, sothat the said plate can be turned similar to an ordinary damper. Oneedge of, the plate is also provided with a weight b to hold the 'platehorizontally, the said Weighted edge resting on a support a while theopposite edge bears against the 6 5 under side of a similar support orshoulder a The partitions at one side of the casing are provided withavertical wall b for the purpose'hereinafter stated. The drum may beprovided with horizontal plates only, as shown in Fig. 3, or it may beprovided with boxes 0, projecting alternately from opposite sides, asshown, in Figs. 1 and 2, the said boxes opening out at the sides of thecasing or drum' to permit air to pass through the drum and be heated. Byproviding these boxes an increased heat-radiating surface ispresented,1and said boxes may be used as shelves for keeping food warmwhen the drum is used over 'a cook-stove.

In the bottom of the drum at the side opposite the connecting-pipe a isan opening D, through which the soot drops from the drum when cleaningsame, the said opening having a pipe d with a door d.

To provide for cleaning the drum when the boxes 0 are employed, I usescrapers e, having handles e extending through one side of the drum, thesaid scrapers being located upon the boxes, so that they may be drawn 0across the same.

In cleaning the drum the partition-plates B are each given a half-turn,which will deposit the soot upon the boxes 0, and the soot from theupper box is scraped to the next 5 lower, and so on, until it isdeposited upon the bottom of the drum, from which it is scraped into theopening D and through the pipe d into a receptacle placed at the lowerend of said pipe, the door d being open. 'It will be noted, therefore,that simple and effective means are provided for readily andconveniently cleaning the drum of soot, and

as soot quickly accumulates in a heatingdrum of this character this isan important eature of the invention.

\Vhen the partition-plates and boxes are arranged as shown in thedrawings, the smoke will be caused to pass around the ends of saidplates and boxes in a circuitous passage and heat all sides of the drumor casing to radiate a great amount of heat. Thus the heat from thesmoke is utilized to the best advantage in heating the room. When adirect draft is required, the partitions at one side of the drum aremoved horizontally to bring the plates 12 on a vertical line against theother partitions, forminga straight passage through the drum.

I have shown both the horizontal partitionplates and the boxes and mayuse them in combination oreither one alone,and therefore desireprotection by patent upon either one or both. The drum may be providedwith a damper f, Fig. 3, and may be also provided with a tube h, Fig. 5,under the plates when said plates are used alone, the said tube formingan air-passage through the drum.

The advantage of a heating-drum for utilizing the heat from smoke willbe readily appreciated and will serve to heat a room over a kitchen orroom containing a stove, the particular construction of the drumprovidinga direct draft when needed, forming practically a continuationof the smoke-pipe.

The drum can be cheaply manufactured from sheet metal and can thereforebe sold at comparatively small cost.

Having thus described my invention, I do not wish to be limited in whatis herein particularly shown and described, but reserve the right tomodify or change the construction within the spirit and scope of myclaims.

I claim- 1. In a heating-drum, the combination with the casing connectedat its ends to the stove and smoke-pipe, horizontal plates slidablymounted therein, rods connected to said plates, and a wall at one end ofthe plates, substantially as shown and described.

2. In a heating-drum, the combination, of the casing connected atitsends toa stove and smoke-pipe, horizontal plates swiveled in the drum orcasing, rods connected to said plates, a wall at the outer end of theplates at one side of the drum, and supports for said plates, one edgeof each plate being heavier than the other, substantially as shown anddescribed.

3. In a heating-drum, the combination, of the casing connected at itsend to a stove and smoke-pipe, horizontal plates swiveled in the drum orcasing and located at one end thereof, boxes in the other end of thecasing, scrapers mounted in the casing upon the boxes,and handlesconnected to said scrapers, the bottom of the drum having an openingthrough which the soot is deposited, substantially as shown anddescribed.

In testimony whereof I aflix my signature in the presence of twowitnesses.

WILLIAM VOGEL.
